Demi arrived for the show and went to make her final checks when she discovered Friedman, the show’s choreographer, had interfered and changed her plans.

“Demi was pissed and told the producers this wasn’t what she’s planned and she was not putting her name to it,” a source familiar with the situation told Radar exclusively. “The acts and dancers were all rushed out of the studio to make the changes 10 minutes before the show started.

“Demi had worked hard and spent all week planning performances and styling for her contestants, so to say she was unimpressed that Brian had changed things is an understatement. She knows how important styling and creative is, she wants her acts to look cool and that includes their staging and dancers too.”

“Brian had given Willie’s dancers angel wings to wear and Demi hated them. Plus he’d interfered in what Cece was wearing and Demi thought it looked terrible,” the source told Radar. “She insisted everything be changed back to what she’d planned. She’s told them all no one is to change anything on her acts ever again. She’ll be signing absolutely everything off.”
